Defining quality parameters of color images is a current issue. Nowadays, there are developed international standards regarding color parameters. An important parameter is a comparison of color properties of images. Histogram analysis of saturation of primary colors on tested images is described. By means of PhotoShop or Photo Paint software the average saturation of primary RGB colors and lightness are defined. The proposed measuring method is a simple, inexpensive evaluation of saturation of color image quality.
